dimensions may vary, of course, depending upon the size of the tire. ihe steel strips are resil'ent and they are preferably coated with a rubber compound and vulcanized, thus acquiring a hard rubber surface. The compound preferably is such that the strips will become vulcanized to the strips of rubber between which they are interposed, in the operation of vulcanizing the interliner. This is not indispensable, however, inasmuch as the fabric strips are all thorongnj vulcanized together, so that in any event the steel plates or puncture-proof elements will be firmly held in their embedded position in the interdiner.

The transverse spaces between the outer series of metal strips 4f are preferably of about one-half inch in width; and the inner strips 1l are correspondingly spaced, but are staggered with relation to the outer series of platesF That is, the inner plaies are disposed beneath the spaces between the outer plates, and the outer plates cover the spaces between the inner plates. rlhe steel plates or anti-puncture elements are desirably of sutlicient length to guard affainst pimcturing any portion` of the tread of the tire which is liable to come in contactwith a nail or other punctin'ing element.

'lhe sheets and strips of fabric employed are all rubberized or thoroughly saturated with a solution of rubber; and after the inter-tinta.' has been built up on a suitable core or inarulrcl, it is subjected to the usual vulcanization process, which gives to it a permanentl contour corresponding with the inner surface of the outer casing. It will be understood that in the vulcanizing process, the transverse narrow fabric strips 's' and 7 and the corresponding` fabric strips ist and llt are thoroughly vulcanized to the plies of rubber between wnich they are intcrposed, which are, in turn, vulcanized to the adioinii shet of fabric', and the sheets and strips of fabric are also thoroughly fulcanized together throughout the portions thinking the extremities of the steel plates. Thus, the steel-plates, or arn'ior-elements are firmly secured in their cml'iedded positions, and well anchored by the canvas or fabric, as well as bv the adhesive or vulcanising effect between the metal strips and the adjacent plies of rubber. h'loreov'er, the resilient metal strips are everywhere embedded in. rubber, so that wearing action upon the canvas or fabric obviated in tho use ot' the tire,

'the inter-liner i3 may be vulcanized within the casing A, or may simply be introduced and used vilhout vulcanization, if uesi nl. Vil'hcro t inter-liner is to he l wil hin a casing, this ,",il'teuinjg the film solution to the inter-liner, and then effecting vulcanization in the usual manner.

rihe improvement described not only renders the tire puncture-proof,` but increases 'the longevity of the tire. Any preferred manner of embodying the invention in a tire structure may be employed.

The foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitation should be understood therefrom,` but. the appended claims should be construed as broadly as permissible in view of the prior art.

lVhat l regard as new and desire to secure by Letters Patent is:

l. l tire structure comprising a pair of rubber strips extending through the. great circumference of the structure, a series of interposed transversely extending resilient spaced steel strips having a vulcanized coating thereon, a second pair of similar rubber strips, a second series of interposed resilient steel strips having a vulcanized coating thereon, covering the spaces between the strips of the first-mentioned series, fabric interposed between the pairs of rubber strips and extending laterally beyond the saine, circumferential fabric strips flanking each pairof rubber strips, and outer and inner plies of fabric enveloping the elements inentioned, the structure being suitablyshaped and vulcanized together.

2. A tire structure comprising a pair of elastic rubber stri s, an interposed series of spaced, transversely extending resilient steel strips having a vulcanized coating thereon, relatively narrow fabric strips flanking said rubber strips, and relatively` wide fabric Y plies enveloping the elements mentioned, the

struc' ure being suitably shaped and vulcanized together.

3. A tire structure comprising resilient steel strips having a vulcanized coating thereon, thicknesses of elastic rubber between which said steel strips are interposed, and fabric plies enveloping said thickness of rubber and interposed steel strips, the structure being suitably shaped and vulcanized together.

si. ln a tire structure, an inter-liner, coniprising an outer ply of fabric of a vidtli correspondidom with the transv rse outer circumference of the inter-liner, a pair of elastic rubber sheets adjacent thereto and correspending with the tread portion of the tire, a series of spaced, transverse resilient steel strips interposed between vthe rubber sheets, said steel strips i'iaving a rubber compound vulcanized thereon, fabric strips in the spaces between said sl eel strips, circumferenu tial fabric liinl rubber .s riPSa Lemme fabric strips, a second pair of rubber sheets fabric strips 'flanking said second-name adjacent the inner ply Of fabric, transverse pair of rubber strips, and un inner fabric resilient steel strips between said last-menstrip of greater Width than tbe rubber strips 131 tioned rubber sheets, said.v last-mentioned and the fienking fabric strips, the structure 5 steel strips having a rubber` compound Vulbeing suitably shaped and vulcanized 't0- cunized thereon, fabric strips in the spaces gether. between said second-mentioned steel strips, 'WLLIAM F.
